Why a button of my OP-1 doesn't work?

Hi ! First, thanks a lot for your answer, i didn’t answered you directly cause i wanted to take the time to try it. I remove the board to see under it but i don’t see where the solder are. There is a plastic with kind of cables inside, that connect the keyboard to the op1, but i can’t see where it can be burn or something else.

It's the 2 and roll forward button that doesn't work at all.

It's very hard to pinpoint without physically seeing it. if you have photos, maybe i could determine the path, ultimately, you need to follow the path on your controller board to the switch that is malfunctioning. If you know how to use a volt meter you could check for continuity from the knob connection to the path on the board. its a good way to determine if you have a damaged path on the board or the knob itself.

IMO - most mixers, synths & midi controllers always suffer the same issues, one being damaged knob and secondly the path on the board gets corroded or damaged by humidity, spilled drink, insects etc.

Can Ash from cigar cannabis smoke damage a keyboard faster than a regular user. I’m not sure if I bought a busted op-1 or got puked a fast one on. Because my buttons just gave out each time I factory reset something’s wrong with my op-1. My firmware jumped from242 to 246 could that be a issue I didn’t get update 244 or 245 it wasn’t available no more on TE site . I’m definitely looking at parts here. Or send in for repair??

@mrapplianceorl how do I return the play button back I clicked it out now don’t know how to click it back in from left to right or too to bottom?? I got it to click in bottom but at a loss ?
